I can't see pictures, but I'll try to do what I can.
2+4x+10=1
Combine like terms.
(2+10)+4x=1
12+4x=1
Subtract 12.
12+4x=1
-12 -12
4x=-11
Divide 4.
4x=-11
/4 /4
x=-2.75

Answer:
The time the patient expected to survive after diagnosis is 29 years.
Step-by-step explanation:
It is provided that the mean survival time after diagnosis for a certain disease is 15 years with a standard deviation of 5 years.
That is,
An individual's predicted survival time is <em>a</em> = 2.8 standard deviations beyond the mean.
Compute the time the patient expected to survive after diagnosis as follows:
Thus, the time the patient expected to survive after diagnosis is 29 years.
